This striking 1955 Austin-Healey 100 BN1 roadster boasts a rich history, having participated in Sportscar Vintage Racing Association (SVRA) events before being acquired by its current owner in 1988. A comprehensive refurbishment spanning a decade, beginning in 2000, transformed this classic British sports car. The restoration included the installation of lightweight aluminum Fourintune body panels and a fresh repaint in crisp white. Under the hood, the original 2.7-liter inline-four engine underwent a racing-focused overhaul, enhancing its performance capabilities. Power is now channeled through a modern five-speed manual transmission sourced from a Toyota Supra, offering improved drivability. The car rides on distinctive American Racing magnesium wheels, mounted over upgraded front disc and rear drum brakes for enhanced stopping power. Inside, the cabin has been re-trimmed in stylish blue upholstery, and notable features include a streamlined 100S-style windscreen, a classic Moto-Lita steering wheel, auxiliary fog lights, a custom exhaust system with a unique exit, a Le Mans-style fuel filler, and a pair of performance-oriented SU carburetors. In preparation for its next custodian, the front brake calipers were recently rebuilt in May 2025. This significantly modified BN1 roadster is now offered with a clean Illinois title in the seller’s name.
Lightweight Aluminum Body and Striking Aesthetics: According to the seller, the refurbishment included the fitment of an aluminum trunk lid, fenders, and front and rear clips sourced from Fourintune, significantly reducing weight. These panels are complemented by a louvered hood and original steel doors. The exterior was refinished in a bright white hue, and a low-profile Lexan 100S-style windscreen was installed, enhancing its sporting silhouette. The bumpers were removed during the restoration, further emphasizing its race-inspired design. Additional exterior details include functional driving lights, dual side mirrors for improved visibility, and a purposeful Le Mans-style fuel filler. It is important to note that this roadster does not have a convertible top.
Upgraded Brakes and Lightweight Wheels: The Austin-Healey rides on lightweight American Racing magnesium 15″ wheels, contributing to its agile handling. These wheels are fitted with 168/80 Nankang tires, offering a blend of classic looks and modern performance. A spare wheel is conveniently stowed in the trunk. The braking system has been significantly upgraded with dual master cylinders, 3000-specification front disc brakes, and uprated rear drum brake components, as stated by the seller. Ensuring optimal braking performance, the front calipers were rebuilt, and the entire system was bled in May 2025.
Refreshed Blue Interior: The interior of this BN1 was re-trimmed in attractive blue vinyl upholstery with contrasting white piping on the bucket seats during the refurbishment, creating a stylish and comfortable cockpit. Interior appointments include a passenger grab handle for added security, lap belts for safety, and a dash-mounted rearview mirror.
Classic Moto-Lita Steering and Smiths Instrumentation: The driver grips a Moto-Lita wood-rimmed steering wheel, adding a touch of classic elegance. This wheel frames a set of Smiths instrumentation, including a 120-mph speedometer, a 6k-rpm tachometer to monitor the modified engine, and supplementary gauges providing essential vehicle information. The five-digit odometer currently displays 338 miles; however, the total mileage of the vehicle is unknown.
Racing-Overhauled Inline-Four Engine: The 2.7-liter inline-four engine is reported to have undergone a comprehensive overhaul and modification in the early 2000s, with the installation of race-specific components resulting in a high 10.5:1 compression ratio, promising spirited performance. The engine breathes through a pair of responsive SU carburetors and expels exhaust gases through a custom exhaust system that exits ahead of the left-rear wheel, contributing to its unique character and sound. The seller mentions that the head gasket was replaced, and the coolant was flushed in early 2022. It is also noted that there are some oil drips present.
Five-Speed Toyota Supra Transmission: A significant upgrade to the car’s drivability is the installation of a five-speed manual transmission sourced from a Toyota Supra, utilizing a “Smitty’s” conversion kit. This modern transmission offers smoother gear changes and potentially improved highway cruising. The seller notes that the clutch system was bled in May 2025, ensuring proper operation. Additional photographs of the car’s underbody are available in the gallery.
